Trans 2nd and 3rd gear only

P0753 means that the controller has detected a fault in the Shift Solenoid "A" circuit It's very possible shift solenoid "A" has failed electrically. If you have automatic transmission experience it's probably not too hard to replace but you should check it out electrically before you buy the part. you'd have to figure out which solenoid is "A" and check it electrically. There's no way for me to know if there are other problems with the transmission.
